Looking through the reference manual for this chip on page 111 (RM0403 R7) it looks like there is a DMA peripheral line from CAN 1 and CAN 2 to the DMA module. I can't seem to find any reference to this on the MCAN side though or how to enable it. Does the (Sys 0) mean these lines are only from CAN 1 and CAN 2 on CAN Subsystem 0 (out of the 4 on there and 3 on Subsystem 1) and is the lack of documentation because they are reserved for part of the Serial Boot Mode?
